A: I can tell you have been shopping, and learning a lot in the process. Now you just have to compare characteristics and decide what you want. Sometimes paying for some extra features is not necessary. I do not know how important insulation in the frame and sash of a vinyl window is, for example, because vinyl is inherently non-conductive.

When similar products seem to have very different prices, you need to ask why. Does one company have more overhead than another? Is the cheaper company lacking in the proper insurance? Above all, compare efficiency ratings and warranties. Usually, the seal on dual pane windows is the most likely thing to fail, so the longer the warranty on that, the better.

Finally, choose a window company with which you are comfortable working. Dealing with companies that offer a wide variety of products is also a good idea because they can better match your needs and budget. Finally, make sure they have a good reputation for quality customer service.

To locate reputable window companies, visit Home Advisor, enter a service request, and be matched with the ideal service professional in your area.
